boards: riscv: rv32m1: add support for GPIO debugging

Browse source 
Having a pin toggle when the code reaches a certain point
is really useful for debugging; the infrastructure is already
in place for Nordic boards, so just build upon and enable the
mechanism on the Vega board as well.

Turn on debug GPIO toggling for the BLE Controller. This is useful
when debugging with a logic analyzer or profiling certain sections of
